And as it turns out, her willingness to let it all hang out extends to the nudity in her new film Lovelace, in which she plays porn star Linda Lovelace (which obviously required its fair share of Amanda nakedness).

Amanda recently opened up about her comfort with nudity and took a look back at Mean Girls, calling it her “best work.”

"I still look back at Mean Girls as my best work," Amanda revealed in a recent chat with IndieWire from Sundance. "I was so innocent. I was so green. I look back and I’m like, ‘Really, I thought I was doing a terrible job.’ But it was written so well and so wonderfully directed. [Director] Mark Waters made me look good; he made me funny. And Tina Fey wrote the coolest script of all time. I’m so grateful for every experience."

So is there any chance her buzzed-about role in Lovelace might replace it as her best work? Maybe! “I know that I’m proud of a lot of it," she said. "Certain things I’d like to reshoot but can’t. But I am proud of certain parts of it from an acting point of view. And therefore, I’m not going to roll my eyes and be like, ‘Oh thanks,’ because I really believe in this movie. It’s so nice to believe in something and really love something you’re about to promote."

One might expect a young actress to be uneasy baring all for the cameras, but Amanda has no reservations: "I don’t know why I’m comfortable. Nudity: whatever! Sex: we all do it. There’s a time and a place to be naked. There’s no part in this movie that makes me think, ‘Oh, wow, she’s naked.’ She’s a porn star! We simulated some scenes but there’s no graphic content in this movie, at all. I mean the graphic stuff is when he’s raping me on my wedding night. You see my skirt go up over my head when I’m being gang raped, but it’s like so perfectly done."

Perhaps Amanda's comfort with nudity comes from what isn't shown in the film. There is, apparently, no full-frontal nudity from her or co-star Peter Sarsgaard:

"Both of us are not shy about our private parts. We also weren’t walking around with our genitals out; our bottom-half genitals. That might have been a little strange for me. I don’t really have any interest in people seeing my vagina. It’s just a personal thing. I don’t mind seeing other people’s vaginas. I guess I’m just insecure in that way. Peter… same thing. He was always covered up in that way. I think it’s just our mutual understanding of we needed to be naked a lot of points in the movie and it wasn’t a big deal. It’s like a costume."

Well, don't try wearing it as a costume on Halloween, Amanda... at least, not out of the house.
